Crash after Space Laser Tag bug report

Played for about 2.5 hours total.
Finished the Space Laser tag mission.
Went to the Pause menu>Map and fast traveled back to Sanctuary.
Sanctuary load screen appeared.
Area load finished.
Screen went black. Sound started stuttering in my headsets.
No way to back out, long press on Xbox button did nothing, black screen, console unresponsive.
Rebooted the Xbox by holding power button.
Restarted game, I was (fortunately) in Sanctuary with the Laser tag mission completed.
Did find that all the items I had put in my bank had vanished. Don’t know if this was co-incident with the crash, but that’s the first time I had noticed it.
Super deluxe edition, Xbox One Pro.
